I've got both Poser Pro 2012 and DAZ 4 Pro. I'm still partial to DAZ simply because I am more familiar with it, but I like the way Poser 2012 renders better at least so far. DAZ is getting rather pricey on the Pro version at this point, if you are upgrading from the previous version of both programs it comes to about the same either way though. There are some advantages to Genesis over V4.2 that aren't apparent until you start using it extensively, I'm assuming as it matures it will have all the options V4 has, it is getting pretty close at this point with the morph packs.
